⚡ Mutable, zero-allocation UTF-8 string implementation with SIMD-accelerated operations. Bypasses Java String overhead for elite performance.

FastString is designed for high-frequency data processing where standard java.lang.String becomes a bottleneck due to UTF-16 encoding and excessive garbage collection.

import faststring.FastString;

public class Demo {
    public static void main(String[] args) {
        // FastString works directly with UTF-8 bytes
        FastString s = new FastString("High Performance!");
        s.toUpperCase(); // Native SIMD accelerated (AVX2)
        System.out.println(s);
    }
}

• ⚡ UTF-8 Native: No conversion overhead between network/file bytes and the JVM.
• 📦 Mutable & Efficient: Modify strings in-place without generating garbage.
• 🚀 SIMD Accelerated: AVX2/SSE optimized for searching, case-conversion, and validation.
• 🛠️ Zero Allocation: Designed for 120 FPS UI and high-throughput backend services.
